SPECIFICATION forming part of Letters Patent No. 726,438, dated April 28, 1903.

Application filed May 14, 1901. Serial No. 60,235. (No model.)

To ctZZ whom it may concern:

Be it known that I, PERLEY L. KIMBALL, a citizen of the United States of America, and a resident of Bellows Falls, Windham county, Vermont, have invented certain new and useful Improvements in Separators, of which the following is a description, whereby any one skilled in the art may make and use the same.

The object of my invention is to provide a separator having points of novelty and advantage.

Figure 1 is a sectional view on the line no so of Fig. 2 looking in the direction of the arrows. Fig. 2 is a top View of the separatorbowl with the cover removed. View of the skimming-disk and a small part of the liner. Fig. 4 is a bottom view of the skimming-disk, showing the wings that are secured thereto.

Referring to the drawings, A denotes the separator-bowl, B the cover, and C the liner.

The skimming-cylinder is made up of a series of blades, (clearly shown in Fig. 2,) these blades being secured together at their inner ends by a number of wire rings 66, which pass through holes in the blades. There are six of these rings shown in the drawings. The outer ends of the blades are secured to rings b, which rest in slots formed in the wings and are soldered to them. This construction gives a very light and sufficiently stiff liner to meet all requirements and is extremely simple and inexpensive to manufacture. There are three of these outside rings shown in the drawings. This liner of course fits rather closely within the separator-bowl and rotates with it.

In the bottom of the separator-bowl is located a skimming-disk D, having wings cl formed on its under side. This skimmingdisk has bosses e extending from its periphery, which maintain it in a central position within the bowl. In the center of the disk is an eyelet f of some kind in which to catch a hook for removing the disk from the bowl. To insure the disk moving with the bowl, I set a pin in the bottom of the bowl, which is adapted to enter a hole in the disk. To insure the movement of the liner with the bowl, I file away the inner end of one of the blades of the liner and form upon the skimming- Fig. 3 is a top disk a lug G, which fits between the inner ends of the blades on each side of the one which has been filed off. The circumference of the skimming disk itself is somewhat smaller than the inside circumference of the bowl, so that there is a space h between the bowl and that part of the periphery of the skimming-disk between the lugs through which the blue milk may pass.

The imperforate skimming-disk will skim the milk without the aid of a liner; but when the liner is used in connection with the skimming-disk the construction of the liner is not material, inasmuch as one liner will work with the skimming-disk equally as well as another.

In the operation of the device the full milk is supplied at the orifice O in the cover and passes through the tubes O onto the liner, the cream which is separated from the milk forming a core at the center and passing up and out through the cream-outlet R. The blue milk passes to the inside of the walls of the separater-bowl, runs down between the wall of the bowl and the skimming-disk and underneath the skimming-disk,out through the passages B.

To obtain the best results from the use of cream-separators, it is essential that they be kept perfectly clean as to all of their parts, and by my invention herein shown and described I have produced a separator in which the interior of the bowl is perfectly smooth and has no projections which make it difficult to clean. The liner rests upon the skimming-disk, and by removing the cover and inserting a hook in the eyelet f I am able to withdraw both the disk and the liner, whichin their turn may be separated from each other and thoroughly and conveniently cleansed. The decided advantages of a bowl of this construetion are apparent.

I claim as my invention- 1. In a centrifugal separator adapted and designed for separating mixed fluids of different specific gravities and delivering the whole from the separating vessel in separator prodnets in fluid form, the combination of a separator-bowl, an imperforate skimming-disk located within the bowl, said disk being of slightly-smaller diameter than the interior diameter of the bowl and supported at a distance above the bottom thereof, and a centering device for said disk, substantially as described and for the purposes set forth.

2. In a separator the bowl having a creamoutlet at the top and a blue-milk outlet at the bottom, the liner located therein and an imperforate skimming-disk slightly smaller in diameter than the interior diameter of the bow], and peripheral lugs on said skimmingdisk, substantially as described and for the purposes specified.

3. The combination in a separator with the bowl, of an imperforate skimming-disk located within the bowl, said skimming-disk being slightly smaller in diameter than the interior diameter of the bowl, ribs on the under side of the skimming-disk, and bosses projecting from the periphery of said skimmingdisk and adapted to engage the wall of the bowl, substantially as described.

4:. In a separator a liner made up of a series of plates secured together at their inner ends by a series of Wire rings passing through holes in said plates, and secured at their outer ends by Wire rings located in slots formed in the plates. 4

5. In a separator a bowl, an imperforate skimming-disk located at the bottom thereof, a liner separate from but resting upon the skimming-disk, and meansv for locking the liner and the disk together, substantially as described and for the purposes set forth.
